Wherein, the buffer room 20 has two isolation gates 21. The buffer room 20 is communicated with the isolation room 10 through one isolation door 21 and communicated with the outside through the other isolation door 21. The buffer compartment 20 functions to prevent the isolation compartment 10 from being directly communicated with the outside. For example, when a medical staff member needs to enter the isolation room 10, the staff member first enters the buffer room 20 through an isolation door 21, and in the process, the isolation door between the buffer room 20 and the isolation room 10 is kept closed. After the medical staff is in the buffer room, the isolation door between the buffer room and the outside is closed, and then the isolation door between the buffer room 20 and the isolation room 10 is opened, so that the direct communication between the isolation room and the outside is avoided. It should be noted that the buffer room is widely used in isolation wards.

In this embodiment, the two isolation gates are located on opposite sides of the buffer. Of course, this is only a preferred embodiment and two isolation doors may be provided adjacent to the buffer compartment, depending on environmental requirements.

As a preferred embodiment of this embodiment, as shown in fig. 6, the isolation door 21 of this embodiment includes two isolation door units 211 made of flexible materials that are symmetrical to each other, wherein the top and the outer sides of the isolation door units 211 that are away from each other are fixedly connected to the door frame of the buffer room, the inner sides of the isolation door units 211 that are adjacent to each other and the bottom of the isolation door units are provided with flexible magnetic strips 212, and the bottom of the isolation room is provided with a magnetic attraction structure 213 that is adapted to the flexible magnetic strips at the bottom of the isolation door units.
